‘Cool’ Concrete Touts Fast, Dense Cure

A new concrete claims to eliminate the harmful effects of hydration and the need for expansion cuts, according to Cool-Crete Technology Group.

Cool-Crete is made from Portland cement, sand and stone, but it modifies the typical hydration reaction, resulting in concrete that behaves differently when mixed, the company says.

Cool-Crete has a pH of 11.5 and claims to eliminate the harmful effects of hydration.

The product alters the chemistry through which concrete cures, eliminating the first-phase heat of hydration.

Lower pH

According to the company, Cool-Crete has a pH of 11.5 and eliminates chemical burns.

The product is less porous than conventional concrete and thus less susceptible to the freeze-thaw cycle, according to the company. It also shrinks less while drying and is denser when fully cured. Additionally, Cool-Crete resists slab curl and cracking.

Cool-Crete does not require saw cuts or caulking, can be poured in hot weather, and is ready for use at four days with a strength of over 6,700 psi at seven days, according to the company.
